Gore said he expects a tough game Sunday in Minnesota, against the Vikings' fifth-ranked defense featuring twin sumo wrestlers at tackle in Pat and Kevin Williams (no relation) and relentless defensive end Jared Allen.

"As long as we execute and keep the ball, we should be fine," Gore said. " I'm going to go out there and try to be the best guy on the field."

"Right now, Snyder is going a good job," Singletary said. "He stepped up yesterday, did a good job. As long as he does that, we'll be in good shape."

Both Snyder and Pashos gave up sacks Sunday, but Singletary said the right-tackle position "really isn't an area of concern right now."

Sack a game: At the pace he's going, defensive end Ray McDonaldwill finish the season with 16 sacks. He had one each in the first two games. Fourteen more in 14 games would suit the third-year player just fine.

"That's the plan," he said. "It's studying film during the week, knowing what my guy is doing, figuring out a way to beat it and applying it on Sunday."
